Robot-Assisted Surgeries

Posted blbahnPosted in Health and Medicine, News, Technology

By Neha Madugala, Cognitive Science, ‘22 Author’s Note: I came across an article detailing the future of surgery. What initially seems like science fiction may be becoming a reality as more and more surgeries are being administered by robots. Through my research, however, I found that robot-assisted surgeries may have the initial appeal of lowering human error, but there are still various issues that must be resolved before they can fully take over in the surgical room.    Robot-assisted surgeries boast the potential of shorter recovery time, less pain and blood, and fewer scars and infections. They have been on the market for a little less than twenty years, and have been used in cancer procedures for about the past […]

Looking Deeper into Life: How a Nobel Prize Winner Advanced Microscopy

Posted Aggie TranscriptPosted in News, Technology

By Madison Dougherty, Biochemistry and Molecular Biology ‘18   Author’s Note: “I was encouraged to attend and review Nobel Prize winner Eric Betzig’s lectures on campus, and I am extremely glad that I did. As a Biochemistry and Molecular Biology major, I did not think that I would find microscopy very interesting, but after listening to Betzig talk about his developments in the field, I felt a new sense of appreciation for microscopy, and even for telescopes and space. If you are interested in astronomy, physics, chemistry, biology, or all of the above, I highly encourage you to watch and absorb the wealth of information that he has to share with the scientific community. Full video presentations of Betzig’s lectures […]

Stem Cells: Important Yet Controversial

By: Lauren Forsell, Biological Sciences ’16 and Parnya Baradaran, Computer Science Engineering, ’16 Author’s Note:  “Parnya and I collaborated on this piece for a Science and Religion: The Case of Galileo seminar assignment. This assignment was inspired by the seminar’s focus on religious controversies surrounding scientific advancements, theories, and concepts. Another main reason why we wrote this piece is because of our backgrounds. Parnya, a computer engineer major, and myself, a biology major, both attended Catholic high schools. We enjoyed writing this piece because analyzing science and technology in the face of religious teachings and practice is something we will have to consider in our future careers. We chose to analyze abortion because it is one of the most popular […]

Data Reproducibility: The Chink in Science’s Armor

Posted Aggie Transcript2 CommentsPosted in Technology

By Christopher Fiscus, Biotechnology, 2015 Science is an additive discipline in which each novel contribution builds upon the breadth of existing scientific knowledge and acts as a launch pad from which to pursue further study.  The scientific community is currently in the midst of a crisis: many studies are not reproducible, meaning that results cannot be adequately verified by other scientists.  According to estimates, approximately 75-90% of preclinical studies published in high-impact journals, such as Science and Nature, cannot be replicated (Begley and Ioannidis 2015).  This lack of reproducibility undermines science as a vehicle for human progress as it means that new research avenues are being pursued based on presumptive hypotheses and unverifiable findings.  The result is a widespread waste […]

Mapping neurons through online gaming

Posted Aggie TranscriptPosted in News, Technology

By: Jenny Cade, Biochemistry & Molecular Biology ‘15 One of the biggest challenges in neuroscience today is mapping the wiring of the nervous system. Looking at the spatial arrangement of neural networks can tell us a lot about how information is relayed, but accurate 3D mapping of neurons is an enormously challenging task, even with the aid of computer analysis. One group of researchers at MIT has harnessed the power of crowdsourcing to tackle this problem.

New Method Increases Supply of Embryonic Stem Cells

Posted Aggie Transcript2 CommentsPosted in News, Technology

By: Varsha Prasad, Genetics ’15 A study to employ a new method of generating human embryonic stem cells without destroying any human embryos is currently being conducted by an international research team led by Karl Tryggvason, Professor Medical Chemistry at Karolinska Institutet and a Professor at Duke-NUS Graduate Medical School in Singapore. The researchers developed a method in which embryonic stem cells can be obtained from a single cell of an eight-cell embryo, which can then be refrozen and placed in the woman’s uterus.  This prevents the need to destroy human embryos in the process.  The idea is that the embryo can survive a single cell removal.
